Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed November 9, 1915. Serial No. 60,521.

To all whom t may concern Be it known that I, SAMUEL F. HUBBARD, a citizen of the United States, residing at Talladega, in the county of Talladega and State of Alabama, have invented certain new and useful Improvements in Wheel-Clamps, of which the following is a specification.

This invention relates to wheel clamps, and aims primarily to provide eflicient means for assisting in the operation of moving the truck box of a railway car relative to the journal of the wheel forming a part of the truck, for the purpose of inspection or repair of any of the parts within the truck box.

A further object of the invention is to provide a means in combination with an ordinary lifting jack whereby the wheel and journal of a railway car may be held firmly in lowered position, while the truck box is moved by operation of the jack for the purposes above mentioned.

A still further object of the invention is to provide an eflicient means for attaining the above recited ends, which shall be of simple construction, cheap of manufacture, easy and quick of application to a car wheel, and which will prove thoroughly eiiicient in operation.

IVith these ends in view, together with others which will appear as the description proceeds, the invention consists in the novel combination and arrangement of parts, all as will be described more in detail hereinafter, illustrated in the accompanying drawings, and particularly pointed out in the claims.

The invention will be best understood by reference to the accompanying drawings, wherein- Figure 1 is a vertical section through a car wheel and journal box of conventional form illustrating the application of a wheel clamp constructed in accordance with my invention, and Fig. 2 is a detail perspective view of the improved clamp.

Referring more particularly to the drawings, 3 represents a car wheel, to which is fixedly secured the axle 4i, providing the usual journal 5 housed within a boxing 6, all as is readily understood by those familiar with the construction of railway car trucks.

In raising the truck boxing 6 to permit of inspection or repair of any of the parts contained therein, a jack 7 of the lifting type is usually employed, and it is the usual experience-in the operation to have the journal of the axle follow the boxing in its upward movement. To overcome this objection, that is, to retain the axle and journal in proper lower or ixed position while the boxing is being moved vertically, I provide a simple and efficient means, consisting in a base providing a plate 8, having an arm or support 9 projecting therefrom to extend adjacent the wheel 3 of the car. The base 8 is of suilicient dimension to accommodate and support the lower end of the jack 7, it being intended in use to interpose the base or plate 8 between a railroad tie or road bed and the base of the jack 7 to securely hold the improved wheel clamp in proper position. The wheel clamp may be formed of substantially thin yet strong material, of suiiicient rigidity to withstand the strain to which the same may be subjected, and the arm 9 extends upwardly and outwardly from one edge thereof as shown, and having at its extreme end an upturned llip 10. The said arm is provided preferably at the juncture of the lip with the extreme end of the arm with a threaded aperture l1, the same being preferably angularly disposed to receive the threaded shank of a screw bolt or set screw 12. By this arrangement it is apparent that upon application of the improved wheel clamp to the truck of a car as shown in the drawings, with the free end of the arm 9 adjacent the car wheel and the screw bolt 12 operated to impinge at its lower end against the rim of the wheel, movement through the jack 7 of the truck box 6, in a vertical direction may be accomplished without movement to the journal box 5.

The extreme simplicity of the above described device rendcrs the same applicable to cars employing trucks of varied constructions and while I have shown the preferred embodiment of my invention in the accompanying drawings, it is to be understood that I may make such changes in the minor details of construction as I may see fit without departing from the spirit of the invention.

I claim:

1. In combination with a jack; a plate, the said plate adapted to support said jack, an arm formed integrally with said plate, and extending upwardly and outwardly from one side thereof, an upwardly disposed lip formed upon the extremity of said outwardly extending portion of said arm, and a set screw threaded through said arm at the juncture of the lip with the outwardly and the Said erin being provided with a extending portion thereof, sind screw prothreaded opening at the juncture of the hp jecting downwardly and outwardly therewith 'the erin, substantially as described.

from, substantially as described. n testimony whereof I a'HiX my signature 2. is n article of inzlrnufacture; a pllate, in the presence of two witnesses. an arln orined integra ly with said plate and extending upwardly und outwardly SAMUEL F HUBBARD from one edge thereof, a lip formed to eX- `Witnesses: tend upwardly troni the extremity of the W. C. DowDELL7 i0 outwardly extending portion of said arm, W. W. KINGSBERY.
